Based on a quick Google search I'm defo not the only one asking for the first Adam- game to be published on Android, as I'm only able to play the second. 

Playing this on an android tablet and found myself using the galaxy tab pen, as the game is too sentitive to touch on dialogue choice area (registers my choices wrong before I even manage to properly push on my dialogue answer) but doesn't register touches well when looking for clues or pausing the game. Using Samsung's own pen, it's easier to play and navigate.
